To convert a vector graphic to a bitmap
1 Select an object.
2
Click Bitmaps Convert to bitmap.
3 Choose a resolution from the Resolution list box.
4 Choose a color mode from the Color mode list box.
5 Enable any of the following check boxes:
• Dithered — simulates a greater number of colors than those available. This option is available for images that use 256 or fewer colors.
• Always overprint black — overprints black when black is the top color. Enabling this option prevents gaps from appearing between
black objects and underlying objects when you print bitmaps.
• Anti-aliasing — smooths the edges of the bitmap
• Transparent background — makes the background of the bitmap transparent
You can change the black threshold for the Always overprint black option. For information about setting the black threshold, see
“To set the overprint black threshold” on page 590.
If you export a vector file to a bitmap format, such as GIF, you are prompted to set the bitmap conversion options described in the
procedure above before you export the file.
Making the background of a bitmap transparent lets you see images or a background otherwise obscured by the bitmap background.

8 Enable any of the following check boxes:
• Dithered — simulates a greater number of colors than those available. This option is available for images that use 256 or fewer colors.
• Always overprint black — overprints black when black is the top color. Enabling this option when you print bitmaps prevents gaps
from appearing between black objects and underlying objects.
9 In the Options area, enable any of the following:
• Anti-aliasing — smooths the edges of the bitmap
• Maintain layers — preserves layers
• Transparent background — makes the background of the bitmap transparent
You can change the black threshold for the Always overprint black option. For information about setting the black threshold, see
“To set the overprint black threshold” on page 590.
Not all options in the Convert to bitmap dialog box are available for all bitmap file formats.
Making the background of a bitmap transparent lets you see images or a background otherwise obscured by the bitmap background.
